Wrong type narrowing with Boolean(expression)

[Felix-Indoing]

TypeScript Version: 3.8.3

Search Terms: Boolean type narrowing

Code

 const x: {test: string} | null | undefined = something()

 // this works
 if (!!x) {
 console.log(x.test)
 }

 // this can not work
 if (Boolean(x)) {
 console.log(x.test)
 }

Expected behavior:
Expression inside the second if statement should work.

Actual behavior:
The second if statement gives the following error:

TS2533: Object is possibly 'null' or 'undefined'.

Unfortunately changing Boolean declaration breaks cases with filter etc.
